an improved means for creating fa condi-V tion of unbalanced .pressure between the'interior. of the bottle and the surface of the source of supply with whichl the-short leg of the Siphon communicates.

Y To the accomplishment of this'object,

such others as may hereinafter app ear,f,the .y

various features ofthe invention relates to certain devices, combinations and arrangements of parts, Vhereinafterldescribedwand then set o'rth'lindetail in thefapjpend'ed claimsl which possess advantages readilyA apparent to those .skilled in the art.

The various features of the present invention will be readily understood from an inspectionV of the accompanying drawings illus- Y /trating thebest form of the, invention at present knownto the inventor, in which,

Figure 1 is a view in elevation of a bottle-llling device ada ted to be connected to Y the long leg of a sip on;

Fig. 2 is a view in sectional elevation shows tube 15 1s an outlet shell 22 having'internal ing how the valve is unseat'ed from ythe valve 3@ seat vwhen the device is engaged with the l mouth of the bottle to be filled g'Y Fig. 3v is a view similar toy Fig.l 1 except that the bulb is removed'and the parts are n broken away to show the internal construction;

Fig. 5 is a detail view Fig. Gis a detail view in sectional elevation on'the line 6-6,Fig. 5. i Referring tothe drawings, the device 5 (Fig. 4) is adapted to be connected to the long -leg 6 of a siphon, the shortv leg 7 of which is inserted into 'aV source of liquid slipply suchVv as the barrel- 8. vSiphons of this type have a varied general useV in bottling beverages and in draining aquariums, fish Astore tanks, wash boilers, washing machines,A

Fig. 4 is,` a view in elevation showing theV device connected to the longleg of a siphon in Sectional plan oit"l Sponge -Qwhch' batteries, gasoline tankson automobiles and i 'thelike .v j y' The device 5 comprises afhollow shell providedwith a central enlargement 10 and cylindrical ends '11 and 12 of dierent diameters, the end 11 beingy smaller than the endf- 12. Mounted on the large end 12isa rubber stopper 13` adapted to tightly the 'moutli'of a bottle 1d. Fitted tightly to the 'smallend 11 of the shell is ahollow tube 15` which extends downwardly through the large end 12 of the shellinto the interior ofthe. bottle, the construction being such that `an air conduit .16 `and an air chamber 17 are formed between the 'exterior of the tube 15 rvandthe interior of they large end 12 of the shell and the interiorof theenlargement 10,

respectively.

The hollow tubey 15,V near its upper end 'is' i provided with a' series of apertures 18.l Upon its'upper end the tube 15 is provided with a rubber disk 19l interposed between two metarwashers 2O smaller in 'diameter than lthe disk 19. 'The disk'19V and the washers 20 .are held in place by a headed scr'e`w21 which fits into and closes the' the hollow tube 15.V

Slidably'mountedrupon the exterior of the threads' engaged'by external threads on an inlet shell 23. The shells are provided with" shoulders which embrace a rubber washer 24k to prevent leakage. `The inlet shell 23 is fitted to the l-ower end of the'long leg ofthe siphon so that liquid mayliow thereupper 'end of i" from'into a'liq'uid chamber 25 formed by the.,

shells. This chamber 25'is provided withy a acts as a .lterfmedia for vthe lIn order to 'niaintlainithe disk 19, consti-M tuting a valve, engaged with a valve seat 27 y 1(Figs, 2 and 3.) formed on the outlet shell 22 a coiledspring 28 is interposed between the air 4chamber shell and the liquid chamber shell. As shown in Fig. 3 the vspring 28'norma-lly maintains the valveV seat 27 engaged" with the valve 19 thus to prevent the. liquid in the liquid chamber 25 from ,liowing'zinto the tube 15 throughthe apertures'18.

:To unseat the valve 19 fromth'e valve seatn 27 to permit the liquid in the liquid chamber 25 to flow through the apertures .18 into the hollow tube 15, the stopper 13 isinserted into theinouth of the bottle 14 and the shells 22 and 23 are moved downwardly as a unit on the-tube -15 against the tension of the spring v28. Asv shown in Fig. 2 Athe liquid inthe liquid chamber is free to flow through the apertures 18 into the hollow tube 15.

In Order t@ Wthdrairairifipm theiiiite-y lair from the bulbplassing into the, air charnber 17 ,When the bulblcollapsing"pressure isreleasedthe,check-valve 32fcloses and 'the A,check-valve 31 openstopermit air from the interior of theV bottle to flow through the conduit 16 and air chamber 17 intothefinterior of the bulb4 from which theair may beexpelled bythe next succeeding collapsing movement of the bulbuiider hand pressure.

The bulb is used to startthesiphoiiaction.

` l/VlienV a. lbottle is filled downward. pressure .onthe liquid chamber 25 released top'erinit the spring 28V to close the yyalve and the stopperVv 13 is removed from the mouth fof the illed. bottle. rlfhe stopper y13 is-tlil i11- serted into `the mouth of` any empty bottle and the'shells22 and 23v pressed downwardly i H tonnseatlthe valve 19 frein theyalve and'thus .cause the liquidiii theliquid chainber 25 to fiowthrough theape-rtures lgfrlto Atheghollow tube 15V. `The ,laiiinfthe:yempty Y .bottleis expelled bytheenteringjliquid into the lair ychamber 17 fromwhich V,it"injc'iydie withdrawn by a` few hand closing'movements of the bulbSO. y I The provision of a haiidbulb as apart of Qth'ejbottle Yfilling device renders theE device selfcontained, and thuspermitsit tobe used where4 hydraulic air exhausting Vmeans, not available. The hand bulb alsopermitsthe Abottle filling Vdevice to operate advantageously where the bottle to be filled is located well above the surface of the source of Aliquid 6111101115- R ferring to 4 the lshort leg 7,1ofthe `Siphon fits over a hollow tube carried by .a lcylindrical'piece of wood 34 adaptedto lfloatupoii Ythe surface of .the liquid in the ,barrel 8. .The ,float 34 is provided with a central cylindrical chamber 8,5 which commu- I.nicates ywith a frusto-conical,chamber36 The entrance tothe chamber 36 iscovered with apiece of circular cloth 37 constituting a filter media which is held inpo'sition by a hoop 38 mounted to clamp 4a peripheral upturned skirt 39, on the cloth 87, to the peripheral surface of the float 341. With this construction all the liquid drained from the barrel 8 passes through the filter media before entering the siphon. The filter media may` berenioved for ycleaning or replacement 'by removing the hoop 38.
